提出了一种基于粉末冶金工艺制备泡沫金属的方法。该发泡工艺允许生产形状复杂的泡沫部件、金属泡沫夹层板和泡沫填充的中空型材。使用这种方法可以使一系列合金发泡，包括铝、锌、锡、铅和钢。所生产的部件具有闭孔微观结构和高孔隙率（典型范围为40-90%孔隙率）。选定的机械性能的泡沫金属进行评估，包括加载泡沫样品与和没有面对皮肤和轴向破碎的管状结构与泡沫增强。潜在的应用进行了讨论，如轻质结构和能量吸收的军事和民用。
A method for fabricating metal foams based on the powder metallurgy process is presented. This foaming process allows for the production of complex-shaped foam parts, metal foam sandwich panels and foam filled hollow profiles. A range of alloys can be foamed using this method including aluminum, zinc, tin, lead and steel. The as-produced part has a closed-cell microstructure and a high fraction of porosity (typical range from 40–90% porosity). Selected mechanical properties of metal foams are evaluated, including the loading of foam samples with and without face skins and the axial crushing of tubular structures with foam reinforcement. Potential applications are discussed such as lightweight construction and energy absorption for both military and civilian uses.
